In Figure 4, for example, I ran the System File Checker and received a message indicating that it discovered some corrupt files and that it was able to repair them.

The Windows system file checker is such an effective general fix-all that I believe every Windows user should know about it. Its function is simple.

Now that we have updated and potentially repaired our backup Windows 11 system files, we can scan for errors and apply repairs using the System File Checker.
